Saliva drug tests basically involve the process of checking for small amounts or traces of drugs which remain within the saliva when people use certain drugs. In these tests, a strip is inserted into the mouth of the person being checked. The strip gets wet and the presence of certain drugs can be shown by color changes in the strip.
basically is a refined form of plasma with capability to store some trace amount of drug metabolites within a specific period of time. This test is sometimes known as the oral fluid drug test and is majorly used to test for marijuana, opiates, and cocaine, phencyclidine and methamphetamine drugs. Traces of these drugs will create a color band on the strip indicating presence of the drug while a negative result will show no color.

Saliva drug test detection times

Drug detection times simply indicate a specific time in which a test can reveal the presence of a drug in the urine, saliva or hair of the user. The specific time will reveal the first time the drug will show up in your body for the first time you took it and the time your body will be clean. The detection times, usually vary from hours, days to months, depending on the type of drug used, amount, and method of detecting the drug.

Detection times in a saliva test



There are no specific drug detection times when it comes to saliva test. Several factors can affect the detection times, making it vary from hours, days, weeks and months depending on the drug being tested and the amount taken. The most appropriate detection times for saliva test when various drugs have been used include:

  • Alcohol – basically from the time of consumption to 12 hours.
  • Cannabis – This takes a few minutes from ingestion time to a day.
  • Cocaine – Few minutes from ingestion time to a day. PCP – Few minutes from the ingestion time to up to 3 days.
  • Opiates – From an hour of intake up to 3 days.
  • Benzodiazepines – has not been known yet
  • Amphetamines – Takes a few minutes to three days of consumption.
  • Methamphetamine – Takes half an hour from ingestion to up to 3 days.

The saliva detection kits usually come in different shapes and forms from different manufactures. Saliva testing is slowly becoming very popular due to its many advantages. First of all, this testing eliminates the instances of cheating since the process of sample collection is not as hard as in the case of urine where users can simply change the sample. A strip is usually inserted into the mouth of persons being tested and results read on the strip with ease.

Factors affecting saliva drug detection times

Amount of drug ingested can greatly affect the detection times with high amounts showing up much faster than low amounts. The health of an individual can also affect the detection times. Individuals with compromised health are more likely to show the drug presence much faster than healthy individuals. The frequency of usage can also affect the detection times with new users getting very fast detection times. Heavy users will take longer periods before the drug can show up since the body is more adapted to such drugs.


Saliva drug detection times are very essential if the technicians have to properly test for drug metabolites in the bodies of individuals. The only time results can give a false negative is when the detection times have not been reached and users have been tested.
